\tabnotes{6}{This table displays the results of regressions of the average marginal effects of the year dummies (with controls) on the unemployment rate and various functional forms of time using the SOEP data. In the quadratic functional form, \textit{t} is re-parameterized to be equal to \textit{year} - 2016. Column (4) uses a linear spline, while Column (5) uses a trend break. Standard errors in parentheses. *p < 0.05, **p < 0.01 ***p < 0.001}
